There is a transformative power in seeing the familiar from a new, more distant perspective. It’s in this stance that Tranströmer’s narrator is capable of seeing his life for what it is while also acknowledging the lives he might have had. The poem strikes a chord in me because it’s so very sadly and joyfully and devastatingly true. Every life, Tranströmer writes, “has a sister ship,” one that follows “quite another route” than the one we ended up taking. We want it to be otherwise, but it cannot be: the people we might have been live a different, phantom life than the people we are.
